AI Technical Summary
Technical Problem
The sealing rings of existing gate valves need to be replaced frequently due to flushing of fluid media, resulting in large workloads for maintenance personnel.
Method used
A sealing assembly for an anti-leakage gate valve is designed, including a mounting ring, a rigid sealing ring and a first drive assembly. The synchronous movement and replacement of the rigid sealing ring is realized through the transmission device, thereby avoiding the valve body disassembly.
Benefits of technology
It reduces the workload of staff to replace the seal ring, and improves the maintenance efficiency and sealing performance of the gate valve.

Abstract
The invention relates to the technical field of valves, in particular to an anti-leakage gate valve and a sealing assembly thereof, the sealing assembly comprises a mounting ring, a rigid sealing ring and a first driving assembly, a medium channel is formed in a valve body, a gate plate is arranged in the medium channel in a sliding mode, the gate plate or closes the medium channel, and a valve rod is connected to the valve body. One end of the valve rod is located outside the valve body. The mounting ring and the first driving assembly are arranged, when a rigid sealing ring needs to be replaced, a worker pokes a rotating disc with hands, and through transmission cooperation of a transmission rod, a transmission gear, a transmission gear ring, a tray and a transmission unit, the rigid sealing ring can move in a ring groove along the axis of the ring groove; therefore, the rigid sealing rings on the outermost sides of the two annular grooves can be switched, and due to the fact that workers do not need to disassemble the valve body in the process of replacing the rigid sealing rings, the workload of the workers can be greatly reduced.
